(UN News Centre) – The multiplication of crises affecting children since the beginning of 2014 is creating unprecedented challenges that overshadow progress to date to protect them from the impact of war, a senior United Nations official told the Security Council today. The Secretary-General’s Special Representative for Children and Armed Conflict, Leila Zerrougui, said that she was appalled by the total disregard for human life shown by extremist armed groups such as the Islamic State of Iraq and the Levant (ISIL) and Boko Haram. The situation also remains dire in Syria, she said as she presented the Secretary-General’s latest report on children and armed conflict.
